One of the most significant homes in Aurora is the Ford house, designed by architect Bruce Goff. It is also commonly referred to as the "Round" or "Coal" house. Working on the theory that the circle is "an informal, gathering-around, friendly form," Goff designed the home with a center circle 50 feet in diameter and two circular bedroom wings. It is constructed of anthracite coal, steel, glass, cedar, and hemp, and has remained relatively unchanged since its construction.
